You are aiming to spend \$100 or less on meat for a barbeque. Your options are chicken or steak. Chicken costs \$1.29/lb and steak costs \$3.49/lb. How much of each meat can be purchased?

If you wish to spend about 50% of your money on chicken and about 50% on steak, then you have:

\$50 / \$1.29 =~39 Lbs of chicken

\$50 / \$3.49 =~14 Lbs of steak.

So that:

[39 x \$1.29] + [14 x \$3.49] = \$99.17 - total amount of money spent.

\$100 - \$99.17 = \$0.83 - money left over.

Note: if you want to spend all of \$100 on either chicken or steak, you would simply divide \$100 by \$1.29 =~77 Lbs of chicken. Or, \$100 divided by \$3.49 =~28 Lbs of steak. In either case, you will have:

\$0.67 cents and \$2.28 respectively left over. With \$2.28 you could buy one extra pound of chicken for \$1.29, which will leave you with \$0.99 cents left over.

Say you buy no steak at all then all the money goes on chicken 100/1.29 = 77.5 lbs of chicken

Say you buy no chicken and all the money goes on steak 100/3.49  = 28.6 pounds of steak.

I can graph this. You can purchase any amount of the 2 types of meat that lies inside the triangle
